rev. 1.00 5 february 22, 2012 ht77xxs function al description the ht77xxs is a constant on time synchronous step-up converter, which uses a pulse frequency modulation (pfm) controller scheme. th e pfm control scheme is inherently stable. the required input / output capacitor and inductor selections will not create situations of in stability. the device includes a fully integrated synchronous rectifer which reduce s cost s (includes reduce l and c sizes , eliminates schottky diode cost etc.) and board area. a true load disconnect function ensures that the device is completely shutdown. low voltage start-up the devices have a very low start up voltage down to 0.7v. when power is first applied, the synchronous switch will be initially off but energy will be trans - ferred to the load through its intrinsic body diode. shutdown during normal device operation, the en pin should be either high or connected to the vout pin or the vin power source. when the device is in the shutdown mode, that is when the en pin is pulled low, the inter - nal circuitry will be switched off. during shutdown, the pmos power transistor will be switched off thus placing the output into a foating condition. synchronous rectifcation a dead time exists between the n channel and p chan - nel mosfet switching operation s . in s ynchronous rectifcation, the p channel is r eplace d by a schottky diode . here the p channel switch must be completely off before the n channel switch is switched on. after each cycle, a 30ns delay time is inserted to ensure the n channel switch is completely off before the p channel switch is switched on to maintain a high efficiency over a wide input voltage and output power range . application information inductor selection selecting a suitable inductor is an important consider - ation as it is usually a compromise situation between the output current requirements, the inductor saturation limit and the acceptable output voltage ripple. lower values of inductor values can provide higher output currents but will suffer from higher ripple voltages and reduced effciencies. higher inductor values can provide reduced output ripple voltages and better effciencies, but will be limited in their output current capabilities. for all inductors it must be noted however that lower core losses and lower dc resistance values will always provide higher effciencies. the peak inductor current can be calculated using the following equation: l v v v v v i v i out in out in in o out peak l ? + = ) ( ) ( where v in = input voltage v out = output voltage i = output current = effciency l = inductor capacitor selection as the output capacitor selected affects both effcien - cy and output ripple voltage, it must be chosen with care to achieve best results from the converter. output voltage ripple is the product of the peak inductor current and the output capacitor equivalent series resistance or esr for short. it is important that low esr value capacitors are used to achieve optimum performance. one method to achieve low esr values is to connect two or more flter capacitors in parallel. the capacitors values and rated voltages are only suggested values.
rev. 1.00 6 february 22, 2012 ht77xxs layout considerations circuit board layout is a very important consideration for switching regulators if they are to function properly. poor circuit layout may result in related noise problems. in order to minimi s e emi and switching noise, note the follow ing guidelines: ? all tracks should be as wide as possible. ? the input and output capacitors should be placed as close as possible to the vin, vo ut and gnd pins. ? a full ground plane is always helpful for better emi performance. top layer bottom layer top layer top layer top layer bottom layer bottom layer bottom layer
