10 / 27 page 15A Step-Down Regulator with Internal Switches 10 ______________________________________________________________________________________ Pin Description PIN NAME FUNCTION 1, 17, 27, 31, 39, 40 N.C. No Connection. Not internally connected. 2EN Shutdown Control Input. Connect to VDD for normal operation. Pull EN low to put the controller into its 2µA (max) shutdown state. The MAX15035 slowly ramps down the target/output voltage to ground and after the target voltage reaches 0.1V, the controller forces LX into a high-impedance state and enters the low-power shutdown state. Toggle EN to clear the fault-protection latch. 3, 28 AGND Analog Ground. Internally connected to EP1. 4VDD Supply Voltage Input for the DL Gate Driver. Connect to the system supply voltage (+4.5V to +5.5V). Bypass VDD to power ground with a 1µF or greater ceramic capacitor. 5, 16 LX Inductor Connection. Internally connected to EP2. Connect LX to the switched side of the inductor as shown in Figure 1. 6–15 PGND Power Ground 18–26 IN Power MOSFET Input Power Source. Internally connected to EP3. 29 TON Switching Frequency-Setting Input. An external resistor between the input power source and TON sets the switching period (tSW = 1/fSW) according to the following equation: where CTON = 16.26pF and VFB = VREFIN under normal operating conditions. If the TON current drops below 10µA, the MAX15035 shuts down and enters a high-impedance state. TON is high impedance in shutdown. 30 BST Boost Flying Capacitor Connection. Connect to an external 0.1µF capacitor as shown in Figure 1. The MAX15035 contains an internal boost switch/diode (Figure 2). tC R k V V SW TON TON FB OUT =+ () ⎛ ⎝⎜ ⎞ ⎠⎟ 65 .
